The "problem" with healing is that it's no longer a thinking persons job, now it's just "use one spell". I used to complain back in TBC when Hyjal/BT etc. as a resto shaman was literally spamming chain heal (and much of LK as well) but it's even worse now.
Ideal situation for old healers like myself would be a) all self healing abilities out of the game b) the return of down ranking c) get rid of the "slow inexpensive healing spells" modus operandi.
None of which will happen of course, because whack-a-mole is such fun, at least GC and the rest of the inept design team seems to think so.
